UA-001-64 HOBO Water Temperature Data Logger
Data Logger for Hidrology Studies & Water Quality Monitoring.

The miniature HOBO Pendant UA is a waterproof, one-channel temperature data logger.
This 8K or 64K model is value-priced for deployment in indoor, outdoor, and underwater applications measuring relative light levels and ambient temperatures.
Data logger alarm LEDs flash if temperatures have exceeded user-set levels and delay options, and provide visible verification that temperatures have been within the desired range throughout deployment.
The 64K model UA-001-64 stores approximately 52K of 10-bit temperature readings.
The 8K model UA-001-08 has been discontinued.
Features:
- Low-cost temperature logger with alarm status indication.
- Waterproof housing for wet or underwater use.
- Data readout in less than 30 seconds via fast optic USB interface.
